/* LibTomMath, multiple-precision integer library -- Tom St Denis
|

*
|

* LibTomMath is a library that provides multiple-precision
|

* integer arithmetic as well as number theoretic functionality.
|
||||
*
|
||||
* The library was designed directly after the MPI library by
|
||||
* Michael Fromberger but has been written from scratch with
|
||||
* additional optimizations in place.
